failing to runserver - ImportError: No module named 'pysqlite2'

[idannik]

Hi,
I tried to run the django server. However I get the following error :
ImportError: No module named 'pysqlite2'
full log below.

What can be the cause of this error?

Traceback (most recent call last):
File "/home/idan/.pyenv/versions/productionready/lib/python3.5/site-packages/django/db/backends/sqlite3/base.py", line 34, in
from pysqlite2 import dbapi2 as Database
ImportError: No module named 'pysqlite2'

During handling of the above exception, another exception occurred:
